2012-07-24bfin: add 32M, 16M and 8M uncached DMA region optionsScott Jiang1-1/+7
We need larger DMA region to support HD video. Signed-off-by: Scott Jiang <scott.jiang.linux@gmail.com> Signed-off-by: Bob Liu <lliubbo@gmail.com>
2012-05-21blackfin: bf60x: make clock changeable in kernel menuconfigBob Liu1-1/+1
Add clock changeable support in kernel menuconfig for bf60x. Signed-off-by: Bob Liu <lliubbo@gmail.com>
2012-05-21blackfin: add bf60x to current frameworkBob Liu1-0/+5
This patch added bf60x to current blackfin kernel framework. Signed-off-by: Bob Liu <lliubbo@gmail.com>
2011-05-25Blackfin: move internal irq prototypes out of global namespaceMike Frysinger1-10/+0
These are only used in a few internal Blackfin places, so move the irq prototypes out of the global header and into the internal irq one. No functional changes other than shuffling locales. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2010-05-21Blackfin: remove CONFIG_DEBUG_VERBOSE from trace.cRobin Getz1-0/+6
Now that the split traps code has moved all the verbose output to the trace.c file, we can unify all the CONFIG_DEBUG_VERBOSE handling. This gets rid of much of the crappy ifdef forest and enables usage of normal pr_xxx functions so checkpatch stops complaining.

2009-12-15Blackfin: support smaller uncached DMA chunks for memory constrained systemsBarry Song1-0/+6
When working with 8 meg systems, forcing a 1 meg DMA chunk heavily cuts into the available resources. So support smaller chunks to better cover needs for these systems. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-12-15Blackfin: push down asm/ includes and out of bfin-global.hMike Frysinger1-3/+1
Avoid including unnecessary headers all the time as well as circular includes with core requirements. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-10-07Blackfin: mass clean up of copyright/licensing infoRobin Getz1-23/+3
Bill Gatliff & David Brownell pointed out we were missing some copyrights, and licensing terms in some of the files in ./arch/blackfin, so this fixes things, and cleans them up. It also removes: - verbose GPL text(refer to the top level ./COPYING file) - file names (you are looking at the file) - bug url (it's in the ./MAINTAINERS file) - "or later" on GPL-2, when we did not have that right It also allows some Blackfin-specific assembly files to be under a BSD like license (for people to use them outside of Linux).

2009-09-16Blackfin: punt dead cache locking codeMike Frysinger1-5/+0
No one uses these functions, and some are duplicate of existing C code. So just punt the whole thing. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: use generic name for EVT14 handlerPhilippe Gerum1-1/+0
The purpose of the EVT14 handler may depend on whether CONFIG_IPIPE is enabled, albeit its implementation can be the same in both cases. When the interrupt pipeline is enabled, EVT14 can be used to raise the core priority level for the running code; when CONFIG_IPIPE is off, EVT14 can be used to lower this level before running softirq handlers. Rename evt14_softirq to evt_evt14 to pick an identifier that fits both, which allows to reuse the same vector setup code as well.

2009-06-13Blackfin: move custom sections into sections.hMike Frysinger1-10/+1
The Blackfin arch has a bunch of custom section markings for its on-chip regions, but they aren't declared in the right header. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2008-11-18Blackfin arch: rename cache_lock() to bfin_cache_lock()Mike Frysinger1-1/+1
rename cache_lock() to bfin_cache_lock() to avoid namespace collision with common code Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2009-01-07Blackfin arch: SMP supporting patchset: Blackfin header files and machine common codeGraf Yang1-2/+3
Blackfin dual core BF561 processor can support SMP like features. https://docs.blackfin.uclinux.org/doku.php?id=linux-kernel:smp-like In this patch, we provide SMP extend to Blackfin header files and machine common code Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2008-10-27Blackfin arch: don't copy bss when copying L1Mike Frysinger1-1/+1
when copying L1 regions, go to the start of bss rather than end since we have code to zero it out already Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2008-10-10Blackfin arch: bfin_reset() is an internal reboot function ... everyone should go through machine_restart()Mike Frysinger1-1/+0

2008-10-09Blackfin arch: avoid using actual config name in commentMike Frysinger1-1/+1
avoid using actual config name in comment as a text search is done to see what files need to be rebuilt Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2008-10-08Blackfin arch: Use DTEST rather than DMA to poke at L1 SRAM during exception contextRobin Getz1-0/+2
